UNITED STATES HIPIOLYTE HARDY,

PATENT FFICE.

OF PARIS, FRANCE.

ADVERTISING MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 296,956, dated April 15, 1884.

Application filed December 6, 1882. Renewed February 18,1884. (No model.) Patented in France June El, 1882, No. 137,530.

To aZZ whom it may concern:

Be it known that I, HIPPOLYTE HARDY, of Paris, Republic of France, have invented a new and Improved Advertising Musical Instrument, of which the following is a specification.

The device which I have invented is intended to serve as an advertising-card and as a mu sical instrument as well. It is for this purpose characterized by a novel construction of parts which can best be explained and understood by reference to the drawings accompanying this specification, in which Figure l is a view of the parts of the device unfolded. Fig. 2is a view of the same folded and ready for use as a musical instrument. Fig. 3 is a cross-section through the center of the folded device.

The body of the instrument is composed of a sheet, A, of card-board or other suitable stiff material, folded over upon itself along the center line, a, Fig. 1. Through the plies are formed openings b, which register with one ani wood, metal, or other suitable material, which mouth of one who is singing or using the voice, 7

will vibrate and give out a strident sound. The stiff folded sheet A protects the diaphragm sheet B to a great extent from injury. At the same time it can, by removing the cliphandle 0, be readily unfolded whenever it is desired to renew or change the sheet B. Both the interior and exterior of the sheet A can be printed with advertisements of various kinds, as indicated, and the handle 0 also can be used for an advertising medium, if desired. It is indeed with a view to its use for this special purpose that I have designed the an ticle.

WVhat I claim is The folded advertising card A, provided with openings b, in combination with the in termediate reed or diaphragm sheet, B, and removable clip or handle 0, as herein shown and described. I g

In testimony whereof I have hereunto set my hand this 31st day of October, 1882.

HIPPOLYTE HARDY.
